Rareru

Rareru is a Japanese grammatical form that indicates passive voice, potential, possibility, or spontaneous occurrence. It is a suffix attached to the verb stem, often signifying that the subject of the sentence is acted upon by an external force, has the ability to perform an action, or that an event happens naturally or unexpectedly.

The passive sense of raru is the most common. For example, "taberareru" (to be eaten) is derived from the verb "taberu" (to eat). Similarly, "mirareru" (to be seen) comes from "miru" (to see). This passive construction is frequently used when the agent performing the action is unknown or unimportant.

The potential form, also expressed by raru, conveys the ability to do something. For instance, "ikearu" (to be able to go) is formed from "iku" (to go). This potentiality is distinct from explicit expressions of ability and often implies a natural capacity or opportunity.

Rareru can also express possibility, meaning something is likely to happen or can happen. This usage overlaps with the potential form but emphasizes the likelihood or feasibility of an event. Furthermore, it can denote a spontaneous occurrence, where an action happens without deliberate intent, almost as if by accident. The specific meaning of raru is usually determined by the context of the sentence.
